What it is
Auth0 is the established enterprise hosted auth product, owned by Okta since 2021. Comprehensive feature set — SSO, SAML, social logins, MFA, rules and hooks, organisation support. Pricing is enterprise-flavoured. New projects rarely pick it over Clerk in 2026 unless procurement says yes.
Best for
- Enterprises with existing Okta / Auth0 procurement
- B2B products with serious SSO / SAML / SCIM requirements at the enterprise tier
- Organisations needing the mature audit and compliance posture
When not to pick it
Skip Auth0 for new projects with budget flexibility — Clerk, WorkOS, Kinde all serve the same shape at meaningfully lower cost. Skip if your scale exceeds the $200/month tier where the bill becomes painful.
My take
Auth0 is mature and expensive. Most teams who choose it in 2026 are choosing it because the procurement team already approved it; new projects with freedom usually pick something else.
